5.2 Using the sensors
5.2.1 Structure-borne sound sensor for steam traps and valves L52
5.2.2 Surface temperature sensor
If no sensor is connected to the device, you see the words "No sensor" instead of the
ultrasonic level.
ATTENTION !
- Use the sensor holder provided on the shoulder strap of the leather bag if you
need to carry the sensor around with you or whenever it is not in use.
- In the interests of accident prevention, you should also use the leather bag and
shoulder strap to climb stairs or ladders, mount platforms, etc.
Fig. 3
Structure-borne sound sensors L52 are
used to detect ultrasound on solid bodies.
They must be pressed softly against the
test point by hand. To ensure reproducible
results, the pressure force and direction
must be constant.
The sensor is designed for measurements
in a temperature range from -20°C to
+60°C. It can be used to measure hot
surfaces up to 550°C for short periods
(approx. 1 minute).
Note !
- The test procedure can be optimised by varying the device's mixer frequency
(refer to section "6.8 Test parameters") between 20 and 60 kHz in steps of
2 kHz. Changing the mixer frequency directly influences the test values
displayed. To ensure reproducibility, you must perform comparative tests with
the same mixer frequency.

The surface temperature sensor is
designed to measure temperatures from
0°C to 800°C.

The temperature sensor can be connected
to the ARImetec
®
-S either directly or by
means of the hand grip and extension
cable.
